Iran said on Tuesday it had agreed to a visit by EU foreign policy Chief Javier Solana to submit an upgraded package of incentives, a news agency reported. Foreign Minister Manouchehr Mottaki said no date had been yet been set for Solana's trip. The five permanent members of the U.N. Security Council -- the United States, France, Britain, China and Russia -- and Germany, known as the P5+1, offered a package to Iran in 2006 that also required Iran to halt enrichment. Tehran rejected those proposals in 2006 and the latest package is an enhanced version of that earlier offer. "Solana has asked to visit Iran to deliver the P5+1 nuclear incentives package. We have accepted his request," Mottaki told reporters, the students' news agency ISNA said. European diplomats have also told Reuters that Solana was still waiting for Iran to set a time for the handover.
